When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.
[0028] In a first aspect, the present application provides a vehicle thermal management system 10 , which may be a thermal management system for an extended-range new energy vehicle. Figure 1 It is a schematic diagram of the structural framework of an embodiment of the vehicle thermal management system 10 provided in the present application.
[0029] Combination Figure 1 The vehicle thermal management system 10 includes a motor heat dissipation circuit, which is used to dissipate heat from the vehicle's motor system through an internally circulating coolant. The motor heat dissipation circuit includes a heat dissipation trunk 11 and a heat dissipation branch 12 that are interconnected. The heat dissipation trunk 11 is provided with a motor radiator 111, and the heat dissipation branch 12 is provided with components to be dissipated. The components to be dissipated are some components in the vehicle's motor system that need to dissipate heat. At this time, the heat dissipation trunk 11 and the heat dissipation branch 12 form a closed motor heat dissipation circuit. The coolant in the heat dissipation trunk 11 is cooled by the motor radiator 111, and the coolant with a reduced temperature enters the heat dissipation branch 12 to dissipate heat from the components to be dissipated to increase their temperature. The coolant with an increased temperature re-enters the heat dissipation trunk 11 and passes through the motor radiator 111 to cool down its temperature, thereby achieving heat dissipation for the components to be dissipated in the cycle.
[0030] The vehicle thermal management system 10 also includes an intercooling branch 13, which is connected in parallel with the heat dissipation branch 12. A water-cooled intercooler 131, a first medium-temperature radiator 132 and a second medium-temperature radiator 133 are arranged in series in the intercooling branch 13. The water-cooled intercooler 131 is used to dissipate the heat of high-temperature air after being pressurized by the supercharger.
[0031] Specifically, when the intercooling branch 13 is connected in parallel with the heat dissipation branch 12, the coolant in the heat dissipation trunk 11 can be introduced into the heat dissipation branch 12 and the intercooling branch 13 respectively. The water-cooled intercooler 131 can be arranged in the pipeline between the supercharger of the vehicle and the air intake of the engine. The water-cooled intercooler 131 is used to dissipate the heat of the high-temperature supercharged air after being supercharged by the supercharger. The coolant can flow through the water-cooled intercooler 131, and the flowing coolant can exchange heat with the supercharged air to reduce the temperature of the supercharged air. Similarly, the coolant can flow through the first intermediate temperature radiator 132 and the second intermediate temperature radiator 133, and the flowing coolant can exchange heat with the air to reduce the temperature of the coolant.
[0032] In combination with the above content, after the coolant in the heat dissipation trunk 11 is cooled by the motor radiator 111, it is introduced into the heat dissipation branch 12 and the intercooling branch 13 respectively. At this time, the coolant introduced into the heat dissipation branch 12 and the intercooling branch 13 is a coolant with a lower temperature. The coolant introduced into the heat dissipation branch 12 dissipates heat for the device to be cooled, and the coolant introduced into the intercooling branch 13 will dissipate heat through the first medium-temperature radiator 132 and the second medium-temperature radiator 133 in turn, and finally introduced into the water-cooled intercooler 131 to dissipate heat to the high-temperature air. It should be understood that the coolant in the intercooling branch 13 is further reduced in temperature through the first medium-temperature radiator 132 and the second medium-temperature radiator 133, and the coolant with a further reduced temperature is introduced into the water-cooled intercooler 131 to effectively cool the high-temperature air.
[0033] In summary, the intercooling branch 13 and the heat dissipation trunk 11 together constitute a heat dissipation circuit corresponding to the water-cooled intercooler 131, so that the heat dissipation circuit corresponding to the water-cooled intercooler 131 utilizes part of the motor heat dissipation circuit, so that the heat dissipation circuit of the water-cooled intercooler 131 is simple to set and the cost is reduced. In addition, the first medium-temperature radiator 132 and the second medium-temperature radiator 133 achieve a good heat dissipation effect on the coolant, and thus can achieve a good heat dissipation effect on the supercharged air.
[0034] Figure 2 yes Figure 1 A schematic diagram of the arrangement of the first medium-temperature radiator 132 and the second medium-temperature radiator 133 is shown.
[0035] Combination Figure 2 In some specific embodiments, the first medium temperature radiator 132 and the second medium temperature radiator 133 are respectively arranged on the side of the front anti-collision beam 21 close to the rear of the vehicle, and the first medium temperature radiator 132 and the second medium temperature radiator 133 are respectively located at the two ends of the front anti-collision beam 21. It should be understood that due to the display perspective, Figure 2 Only the second medium temperature radiator 133 located at one end of the front end anti-collision beam 21 can be seen.
[0036] Specifically, the vehicle is provided with a range extender (not shown) to generate electricity through the range extender to power the vehicle's drive motor. A front end anti-collision beam 21 is provided on the side of the range extender close to the front of the vehicle, and a front end heat dissipation module is provided between the range extender and the front end anti-collision beam 21. The first medium temperature radiator 132 and the second medium temperature radiator 133 are part of the front end heat dissipation module of the vehicle. At this time, the first medium temperature radiator 132 and the second medium temperature radiator 133 are respectively arranged on the side of the front end anti-collision beam 21 close to the rear of the vehicle, that is, the first medium temperature radiator 132 and the second medium temperature radiator 133 are respectively arranged on the rear side of the front end anti-collision beam 21. In addition, the first medium temperature radiator 132 and the second medium temperature radiator 133 are respectively located at the two ends of the front end anti-collision beam 21, and at this time, the first medium temperature radiator 132 and the second medium temperature radiator 133 can be fixed at the two ends of the front end anti-collision beam 21 respectively. At this time, other components of the front end heat dissipation module may be disposed between the first intermediate temperature radiator 132 and the second intermediate temperature radiator 133 in the vehicle width direction.
[0037] Figure 3 yes Figure 2 Schematic diagram of the structure of the middle part.
[0038] Combination Figure 2 as well as Figure 3 In some specific embodiments, a front air guide 22 and a rear air guide 23 are provided at both ends of the front anti-collision beam 21, that is, a front air guide 22 and a rear air guide 23 are provided at the left and right ends of the front anti-collision beam 21. Figure 2 and Figure 3 Shown in the figure are the front air guide cover 22 , the rear air guide cover 23 and the second medium temperature radiator 133 at the right end of the front end anti-collision beam 21 .
[0039] Specific combination Figure 3 The rear air scoop 23 is located at the rear side of the front air scoop 22 in the vehicle length direction, and the first medium temperature radiator 132 and the second medium temperature radiator 133 are arranged between the front air scoop 22 and the rear air scoop 23. That is, the rear air scoop 23 is arranged at the rear side of the front air scoop 22, and the first medium temperature radiator 132 and the second medium temperature radiator 133 are arranged at the interval position between the front air scoop 22 and the rear air scoop 23.
[0040] In combination with the above-mentioned structural arrangement, the airflow at the front end of the vehicle is introduced into the first medium-temperature radiator 132 and the second medium-temperature radiator 133 through the front air duct 22, and the airflow after the heat dissipation of the first medium-temperature radiator 132 and the second medium-temperature radiator 133 is guided out through the rear air duct 23. At this time, the airflow at the front end of the vehicle is introduced into the first medium-temperature radiator 132 and the second medium-temperature radiator 133 through the front air duct 22 to achieve heat dissipation, and the airflow with increased temperature after heat dissipation is further guided out from the rear air duct 23.
[0041] Through this arrangement, a heat dissipation duct is actually formed by the front air duct 22 and the rear air duct 23, and the first medium-temperature radiator 132 and the second medium-temperature radiator 133 are arranged in the heat dissipation duct, thereby achieving good heat dissipation effect.
[0042] For further specific settings of the front air hood 22, the rear air hood 23 and the first medium temperature radiator 132 and the second medium temperature radiator 133: in some specific embodiments, the side walls of the first medium temperature radiator 132 and the second medium temperature radiator 133 close to the front of the vehicle are attached to the air outlet of the front air hood 22, and the side walls of the first medium temperature radiator 132 and the second medium temperature radiator 133 close to the rear of the vehicle are attached to the air inlet of the rear air hood 23.
[0043] It should be understood that the first medium temperature radiator 132 and the second medium temperature radiator 133 can flow air in the length direction of the vehicle. At this time, the airflow led out of the air outlet of the front air duct 22 can directly enter the first medium temperature radiator 132 and the second medium temperature radiator 133, thereby dissipating the coolant inside the first medium temperature radiator 132 and the second medium temperature radiator 133. The airflow after heat dissipation passes through the side wall of the first medium temperature radiator 132 and the second medium temperature radiator 133 close to the rear of the vehicle and enters the air inlet of the rear air duct 23, and then is led out from the rear air duct 23.
[0044] Furthermore, with regard to further arrangements of the front air scoop 22 and the rear air scoop 23, in some specific embodiments, the air inlet of the front air scoop 22 is directly opposite to the end air inlet of the vehicle's air intake grille, and one end of the rear air scoop 23 away from the front air scoop 22 is connected to the front wheel cover decoration 24 of the vehicle.
[0045] It should be understood that the front end of the vehicle is provided with an air intake grille, which generally extends in the vehicle width direction, and the air intake grille is provided with end air inlets at both ends in the vehicle width direction, and the air inlet between the two end air inlets will be directly opposite to the device located between the first medium-temperature radiator 132 and the second medium-temperature radiator 133 of the front heat dissipation module. By having the end air inlet directly opposite to the air inlet of the front air duct 22, the airflow of the end air inlet can be well introduced into the front air duct 22, thereby ensuring the air intake of the heat dissipation airflow. By connecting the rear end of the rear air duct 23 with the front wheel cover decoration 24 of the vehicle, a relatively good fixing effect can be achieved for the rear air duct 23.
[0046] Continue to combine Figure 1In some specific embodiments, the motor radiator 111 includes a first motor radiator 1111 and a second motor radiator 1112, the first motor radiator 1111 and the second motor radiator 1112 are connected in parallel, and the coolant after the first motor radiator 1111 and the second motor radiator 1112 dissipate heat is introduced into the heat dissipation branch 12 and the intercooling branch 13. That is, the heat dissipation trunk 11 dissipates heat for the coolant entering the heat dissipation trunk 11 through the first motor radiator 1111 and the second motor radiator 1112, thereby ensuring the heat dissipation effect of the coolant.
[0047] Figure 4 It is a schematic diagram of the arrangement of the condenser 14 , the high temperature radiator 15 , the first motor radiator 1111 , the second motor radiator 1112 and the cooling fan 16 .
[0048] Combination Figure 4 In some specific embodiments, the vehicle thermal management system 10 further includes a condenser 14 and a high-temperature radiator 15. The condenser 14 is used for heat dissipation of the air conditioning system and the battery pack system, and the high-temperature radiator 15 is used for heat dissipation of the engine system. The condenser 14 is arranged on the side of the high-temperature radiator 15 close to the front of the vehicle in the length direction of the vehicle, the first motor radiator 1111 is arranged on the same layer on the upper side of the condenser 14 in the height direction of the vehicle, and the second motor radiator 1112 is arranged on the same layer on the lower side of the high-temperature radiator 15 in the height direction of the vehicle. At this time, the condenser 14 is arranged on the same layer as the first motor radiator 1111, and the first motor radiator 1111 is arranged above the condenser 14 at an interval. The high-temperature radiator 15 is arranged on the same layer as the second motor radiator 1112, and the second motor radiator 1112 is arranged below the high-temperature radiator 15 at an interval. The vehicle thermal management system 10 also includes a cooling fan 16, which is arranged on the side of the high-temperature radiator 15 close to the rear of the vehicle in the length direction of the vehicle. The cooling fan 16 draws air through the layer where the first motor radiator 1111 is located and the layer where the second motor radiator 1112 is located, thereby achieving a good heat dissipation effect.
[0049] It should be understood that a relatively good heat dissipation effect can be achieved by providing the first motor radiator 1111 and the second motor radiator 1112. In addition, the first motor radiator 1111 and the second motor radiator 1112 are respectively provided on the condenser 14 and the high-temperature radiator 15, so that these structures can be arranged in two layers. Compared with the three-layer arrangement in the prior art, the arrangement length in the vehicle length direction can be shortened to adapt to the current situation where the arrangement space in the vehicle length direction is shortened.
[0050] In combination with the above contents, the structure formed by the condenser 14 , the high temperature radiator 15 , the first motor radiator 1111 , the second motor radiator 1112 and the cooling fan 16 is located between the first medium temperature radiator 132 and the second medium temperature radiator.
[0051] Continue to combine Figure 1 In some specific embodiments, a two-way valve 17 is provided in the intercooler branch 13. The two-way valve 17 is used to close when the vehicle is in a pure electric driving state so that the intercooler branch 13 is not conductive, and the two-way valve 17 is used to open when the vehicle is in an extended-range mode so that the intercooler branch 13 is conductive.
[0052] It should be understood that the vehicle thermal management system 10 of this patent belongs to the thermal management system of the extended-range new energy vehicle. Therefore, when the vehicle is in the state of pure electric driving, the vehicle's range extender will not work, that is, the engine will not work. At this time, there is no need to cool the engine's intake air, and at this time, the water-cooled intercooler 131 does not need to work. Therefore, when the vehicle is in the state of pure electric driving, the two-way valve 17 is closed to make the intercooler branch 13 non-conductive, which can reduce the working power of the water pump in the circuit to reduce power consumption. When the vehicle is in the extended-range mode, it is necessary to cool the engine intake air, and then the two-way valve 17 is opened to make the intercooler branch 13 conductive and work.
[0053] Continue to combine Figure 1 In some specific embodiments, the heat dissipation branch 12 includes a first heat dissipation branch 121 and a second heat dissipation branch 122. The first heat dissipation branch 121, the second heat dissipation branch 122 and the intercooling branch 13 are connected in parallel. The first heat dissipation branch 121 and the second heat dissipation branch 122 are both provided with a drive motor, and the second heat dissipation branch 122 is provided with a generator 1222.
[0054] At this time, when the two-way valve 17 is opened, the coolant in the heat dissipation trunk circuit 11 can be introduced into the first heat dissipation branch circuit 121 , the second heat dissipation branch circuit 122 and the intercooling branch circuit 13 , respectively.
[0055] Specifically, the first heat dissipation branch 121 is provided with a first drive motor 1211, a first heat dissipation device 1212 and a second heat dissipation device 1213. Among them, the first drive motor 1211 can be a front motor with a peak power of 165KW. The first heat dissipation device 1212 is a three-in-one on-board charger, including a DC converter, an on-board charger and a voltage distribution box, and the second heat dissipation device 1213 is an intelligent driving computing platform. Among them, the second heat dissipation branch 122 is also provided with a second drive motor 1221, a generator 1222 and a range extender controller 1223.
[0056] Further, a first throttle valve 181 and a second throttle valve 182 are provided in the first heat dissipation branch 121, and a third throttle valve 183 is provided in the intercooling branch 13. The first throttle valve 181 is used to adjust the flow of the coolant in the first heat dissipation branch 121, and the second throttle valve 182 can be connected in parallel with the second heat dissipation device 1213 to adjust the flow of the coolant entering the second heat dissipation device 1213. The first throttle valve 181 is provided between the first heat dissipation device 1212 and the second heat dissipation device 1213, and the first heat dissipation device 1212 is located before the first drive motor 1211. The third throttle valve 183 is used to adjust the flow of the coolant in the intercooling branch 13, and the third throttle valve 183 can be provided between the two-way valve 17 and the first medium-temperature radiator 132, and the third throttle valve 183 is located before the first medium-temperature radiator 132.
[0057] Furthermore, the vehicle thermal management system 10 further includes a first water pump 191 and a second water pump 192. The first water pump 191 is disposed at one side of the water outlet of the heat dissipation trunk 11, and the second water pump 192 is disposed at one side of the water inlet of the heat dissipation trunk 11, thereby realizing the circulation of the coolant through the first water pump 191 and the second water pump 192. The vehicle thermal management system 10 further includes an expansion kettle 193, which is connected to the first motor radiator 1111 and the first water pump 191, respectively. The expansion kettle 193 can discharge the air in the first motor radiator 1111 and can also play the role of storing coolant.
[0058] A second aspect of the present application provides a vehicle, including a vehicle thermal management system 10 as described in any one of the above items.
